Disappointing Service

Cell C has been so disappointing lately… I have 3 contracts with Cell C and one of the apparently was due for an upgrade and I only noticed through the statement that the contract ended, they usually discount me as part of the package but this time they did not so my balance was way up than usual. I called in to try understand and the explanation I got was that my contract ended so I was billed without the usual discount. So according to my understanding Cell C has a department that called clients when contracts are soon over and that is to findout if the contract will be continued through upgrade or cancelled. It’s been over two weeks since I inquired only thing I received was the case number, tried to do a follow up but the case was still by the finance department no communication after. My fear was the deduction before they could rectify the statement and discount as usual. The other issue was when I then upgraded the balance from previous contract just disappeared without me being aware that it will happen so I lost out on my benefit though they billed me the full amount. Lastly when I bought the social bundle of R29 with 150minutes as advertised I got 30minutes and when I called they told me that advert was no longer available though it is up until end December this year. I am so furious and disappointed and I feel my loyalty is just not valued and appreciated anymore.
